new_sync_write(): discard ->ki_pos unless the return value is positive

2015-04-12T02:29:46Z

That allows ->write_iter() instances much more convenient life wrt iocb->ki_pos (and fixes several filesystems with borderline POSIX violations when zero-length write succeeds and changes the current position). Signed-off-by: Al Viro

->aio_read and ->aio_write removed

2015-04-12T02:29:43Z

no remaining users Signed-off-by: Al Viro

kill do_sync_read/do_sync_write

2015-04-12T02:29:42Z

all remaining instances of aio_{read,write} (all 4 of them) have explicit ->read and ->write resp.; do_sync_read/do_sync_write is never called by __vfs_read/__vfs_write anymore and no other users had been left. Signed-off-by: Al Viro

make new_sync_{read,write}() static

2015-04-12T02:29:40Z

All places outside of core VFS that checked ->read and ->write for being NULL or called the methods directly are gone now, so NULL {read,write} with non-NULL {read,write}_iter will do the right thing in all cases. Signed-off-by: Al Viro

switch {compat_,}do_readv_writev() to {compat_,}import_iovec()

lift iov_iter into {compat_,}do_readv_writev()

2015-04-12T02:26:45Z

get it closer to matching {compat_,}rw_copy_check_uvector(). Signed-off-by: Al Viro

fs: move struct kiocb to fs.h

2015-03-26T00:28:11Z

struct kiocb now is a generic I/O container, so move it to fs.h. Also do a #include diet for aio.h while we're at it. Signed-off-by: Christoph Hellwig Signed-off-by: Al Viro

fs: don't allow to complete sync iocbs through aio_complete

2015-03-13T16:10:22Z

The AIO interface is fairly complex because it tries to allow filesystems to always work async and then wakeup a synchronous caller through aio_complete. It turns out that basically no one was doing this to avoid the complexity and context switches, and we've already fixed up the remaining users and can now get rid of this case.
